Yesterday I visited some second hand stores. There are a lot of them in Tokyo and they even sell some quality Japanese denim.
Saw a pair of momotaro's, orslow jeans and a lot of flat head in Bingo. I think bingo is the biggest second hand store. Some of the jeans still had the tag attached and the other ones didn't had any fades yet.

If you like monkeys you can go to Nagano, they have a monkeys park nearby where wild monkeys go into the natural hot springs. On the way back towards the Village we stopped by a shrine and even got attacked by a monkey of another group!
Nagano itself was nice and quiet compared to Kyoto and Tokyo. But there are probably way more cool cities to see.
Ps: I'm so jealous of your trips, wish I was able to do that

Should have been loftman
I'm on my way to Tokyo now (unfortunately I'm on the wrong side of the shinkanzen to see mt. Fuji) and I'm hoping I'll have more luck at the kapital stores today
Another tip for people that want to visit Japan: don't go in the summer! It's so hot and humid. Especially when you're doing a lot of hiking and walking it's pretty hard.

Today I visited the lofgren stores in Kyoto today.
I was at the nishiki market for some snacks and the shops are around the corner. They also have other denim related shops. Unfortunately the only jeans that really caught my eye was out of stock in my size.

Really great post and I enjoyed reading it. Seems you guys had a great time and bought some good items.
I'm going to the same cities you went to but a few days later. My girlfriend is not into denim so I couldn't have done a trip like yours.
I'm in the shinkanzen to Nagano right now and will go to Kyoto next, after that we'll have a few days in Tokyo left.
We probably have some time to see a few denim shops but can 't head out to Kojima jeans street for instance. I have no idea what to visit. What are your recommendations?
Also if you have some tips for good for or anything please tell me
